My saga on supporting multiple tenants in ASP.NET Core web applications has come to point where tenants can use separate databases. It’s time now to write some tests for data context to make sure it behaves correct in unexpected situations. This post covers unit tests for data context and multi-tenancy.

This post proposes missing tenant middleware that redirects faulty requests to some public page of company web site.

After some Windows 10 IoT Core updates I discovered that it detected LifeCam Cinema camera connected to it. I tried it also few months ago but then Windows 10 IoT Core was not able to detect it.
